Now, Dorsey is the full-time CEO of Square and Twitter. When Square has its IPO, he'll be the CEO of two public companies.

This could be a risk factor, the company says.

"Jack Dorsey, our co-founder, President, and Chief Executive Officer, also serves as Chief Executive Officer of Twitter. This may at times adversely affect his ability to devote time, attention, and effort to Square," according to its S-1 filing.
